Influence of amaranth dye on the potassium hydrogen oxalate oxalic acid dihydrate (KHOOD) single crystal is investigated. The structural studies were carried out to understand the crystal behavior after dye incorporation. Optical studies were performed to investigate the photon absorption of the crystal with or without the presence of dye molecule. The absorption of pure crystals were also compared with that of amaranth dye-doped crystals and the bandgap was estimated. The surface morphology and the presence of dye molecules are investigated using scanning electron microscope (SEM) and EDX analysis. The elemental mapping was carried out to understand the distribution of elements in the crystal surface. The thermal behavior of the crystal was studied and compared with that of KHOOD and dye-doped KHOOD crystals in detail. The emission properties of the crystals were studied and compared crystal. Field-dependent [Formula: see text]–[Formula: see text] studies were performed to study the conductivity of the crystals and results were discussed in detail.

AbstractThe weathering of hornblende in the Rehiran profile has been investigated by optical, X-ray, infrared and differential thermal methods. Optical studies of the fresh hornblende show that it contains discrete lamellar intergrowths of another amphibole which, from infrared evidence, is of an iron-rich nature. This minor phase is selectively weathered in the lower horizons and yields a clay mineral which was identified as interstratified swelling chlorite-saponite. The major hornblende component remains relatively unchanged. Single crystal photographs indicate that the formation of the clay mineral is not structurally controlled by the parent hornblende, although there is a tendency towards alignment along cleavage planes. The clay mineral becomes unstable in the upper part of the profile and could not be detected in the A horizon. Comparisons are made with the findings of other workers.
